 * SPARK-24294: To bypass scala bug: https://github.com/scala/bug/issues/9554, we catch

 * Note that SparkFatalException should only be thrown from a {@link scala.concurrent.Future},
 * which is run by using ThreadUtils.awaitResult. ThreadUtils.awaitResult will catch
 * it and re-throw the original exception/error.
